The ESGF (Earth System Grid Federation) peer-to-peer (P2P) enterprise system is now the official site for CMIP5 model output.

CMIP5 is the fifth phase of the Coupled Model Intercomparison Project, an initiative launched by the Working Group on Coupled Modeling (WGCM) to promote a new set of coordinated climate model experiments, involving major climate modeling groups from around the world.

CMCC supported the set of simulations required by CMIP5 with a series of experiments performed through its specific climate model, implemented in several configurations.
